This is a genuine TOYOTA replacement reserve tank assembly, specifically designed for TH models with part code 164700H060. The reserve tank, also known as an expansion tank or overflow tank, plays a crucial role in your vehicle's cooling system. It holds excess coolant that expands when the engine heats up, preventing pressure buildup and potential damage to the radiator or hoses. As the engine cools, the coolant is drawn back into the system, maintaining the optimal coolant level. This ensures consistent engine temperature and prevents overheating. Replacing a damaged or leaking reserve tank is essential for maintaining the integrity of your cooling system and preventing costly repairs. This TOYOTA part guarantees a perfect fit and reliable performance, just like the original component.
